Okay, what confused me was that the total reward number was more than confirmed + unconfirmed.

Forgive me if this has already been covered; I did some searching and came up empty.  I'm just starting to dabble here, and the total reward doesn't seem to add up.  Here's what I'm seeing:

Estimated reward: 0.01120823 BTC
Unconfirmed reward: 0.10141200 BTC
Confirmed reward: 0.16376258 BTC
Total reward: 0.44276681 BTC

Thanks!
